Method for Improving Cognition and Motor Timing - A method of training a subject to improve anticipatory timing includes presenting the subject with multiple sequences of stimuli, receiving sensor signals associated with responses by the subject to the stimuli, and recording response times in accordance with the sensor signals, wherein the recorded response times are associated with the responses by the subject to the multiple sequences of stimuli, and wherein the response times have an associated distribution. The method further includes analyzing the distribution of response times for the subject to determine variability in anticipatory timing of the subject with respect to the stimuli, and generating a subject feedback signal corresponding to a result of the analyzing so as to train the subject to improve anticipatory timing of the subject.

SYSTEM AND METHOD FOR GENERATING CUSTOMIZED VISUALLY-BASED LESSONS - An interactive visually-based educational system and method that provides improved teacher-student, parent-teacher and teacher-teacher communication and collaboration. A plurality of data, such as video files, audio files, image files, document files, lesson templates, animations and the like, are received from a teacher, a supervisor, and the like, via a computer network. The received data is stored in a dynamic digital image library. The dynamic digital image library includes means for organizing the received data into easily identifiable and searchable curriculum categories. The received data is further used for generating visually-based lessons corresponding to the plurality of categories associated therewith, which lessons are stored in a digital interactive visual lesson library. The stored visually-based lessons are customized using personalized and other additional data and stored. The customized personalized visually-based lessons are interactively accessed via corresponding applications by associated students, teachers, and parents.
